Referring to the drawings, and

larlyto Figures 1 to 4, inclusive,

more particuit will bes'een of the shells.

The inner shell S is made upof two tub-like sections designated at l and2, the edges of the body portions of thaopen ends of which are broughtinto abutting relation and welded together asat 3. Preferably, the

closedends or heads 4 of the sections- -of the inner shell are dished orcrowned as shown in the drawings.

The jacket orfouter shellJ, is also made up of apair of tub-likesections designated at 5 and 6 which surround the sections of the innershell in the assembly although disposed in spaced relation thereto.

The edges of the open ends of the body portions of the sections 5 and 6of the outer shell are bent back or curled as and these curls arebrought into indicated at 1 abutting relati'on and welded together as at8. In this respect the container of the present invention 'embodiesfeatures described and claimed in my application for Metal barrel, filedNo Serial No. 696,755.

vernber 6, 1933,

1934, Serial No. 748, 31 9." A tap" bushing designated generallyat I2 isprovided in the top of the barrel and is of conven; integrally formedtherewith outwardly directed corrugations above and below the bungbushtional construction, although combined with th e inner and outershells .of the barrel ina*-n'ovel manner.

and 2, the tap bushing 12 is a forging and-its peripheral portion at itslower or inner end is,

Iwelded to the upper head 4 offitheinner shell as indicated at W. Priorto welding the'tapbush ing to the inner shell a protective ring or:annulus of;

metal I! is slipped over the bushing and held up against thelugs '12"thereof by tack welding or in any other 'suitableinanner. After the weldW has-been formed the ring IT-is released-from the lugs I2 and dropsdown to the position shown in the drawings. 'Its purpose is to protectthe Weld W during the "formation of the'weldl8 which 'unitesthemar'gino'f the tap' opening in the outer head'l 0 to the tap bushingintermediate its ends. In forming the weld l8 sufficient metalisfsupplied to fill in the opening in-the head of theouter shellorjacket J. p

A bung bushing 16 which may also bea metal forging is provided betweenthe inner and outer shells and is welded to the innershell as indicatedat I6 and the outer shell as indicated atHGP. The Weld l6 may be betweenthe margin of an opening in the inner shelland a shouldered portion|6"'of the bushing I'G: Similarly, the weld W employed between the tapbushing and the inner shell may be between a portion of the inner shellwhichabutsa recessed or'shouldered portion 13 of the tap bushing." Itwill be seen'from the foregoing that the tap buShi'ngI-Z' and bungbushing l6 mechanically interconnect the inner and outer shells at twopoints and'thereby tend to maintain'the same in proper spaced relation.In this action these bushings are aided by the insulations H andI.In-some instances; however, the inner shell shifts or tends to' shiftwith respect tothe 'outer shell and where shifting occurs stress isbuilt up at thetwo points where the inner shell is secured to the outershell, namely, in the region of 'th'e tap and bung bushings. Thisconcentration of stress may result in fracturing either the welds or theinner shell at or near either one of these two points. Thereuponle'akageof the contents will take place between the 'inne'r and'oute'rshellsand the container is rendered unfit for use. if

The present invention proposes to preclude any such concentration ofstres s'and consequent fracturing and leakage and accomplishes this byproviding means whichcoacts with the bung and tap bushings to provide athree-point suspensionof the inner shell on the outer shell. Ineffecting this three point suspension a steel circular plate 20 which isof approximately the same gauge material as the inner shell is welded asat 2| to the exterior of thelowerend head 4 oppositethe low point L'ofthe inner shell.' A hole 22 which may be approximately one-inch i'ndiameter is punched or drilled in the outer shell in such position thatit will come directly under the plate 20 when theashells are assembled.After the weld 8 has been formed the portion of the In the structureshown ins-Figures, 1...; o o

' aroundpthe, ;barr el:and provide rolling hoops -.which improvethehandling of the barrel in that ;they make it possible to roll the barrelin a straight line without the use of skids. The hoops outer shell whichsurrounds the opening 22 is then welded as at 23 to the plate 20. Thiswelding may be just simply a bead between the margin of the opening 22and the plate 20 or the hole 22 may be entirely filled up by supplyingadditional metal during the welding operation.

With this construction the inner shell is supported on the outer shellat three points and in such manner that relative shifting andconcentration of stress is avoided. ;In addition to the foregoing, theouter shell has ing. l6.. .-These corrugations extend entirelyVinvention'and to' realize certain other purposes may be varied,although in all instances it is usually desirable to have these bushingsnot only serve'their purposes in'co'nnection with the cleaning'andfilling and dispensing of the contents but also to mechanically functionin maintaining the inner and'outer'shells in proper position relativetoeach other," Thus, as illustrated in Figures 5 and 6; the tapbushing-there designated at which is substantially similar to the tapbushing 12 and of conventional construction in its main features, may berecessed orcutaway as at 3| to permit of the hanging up of the portion32 of the upper end head 4 of the inner shell S, as illustrated inFigure 5. The portion 32, which is the marginal portion of the openingprovided in the upper head 4 for the tap bushing, is then welded tothetap bushing'as indicated at 33. The outer peripheryof the'inner end ofthe bushing is also welded to the upper end head 4 of the inner shell asindicated at'33. As in the other embodiment of the invention, aprotective ring or annulus of metal designated at IT is provided inorder to protect the weld 33" during the formation of the weld l8between the portion H! of the upper end head of the outer shell orjacket J and the intermediate portion of the bushing 30.

A somewhat similar though specifically different means is provided fororganizing the bung bushing, shownin Figures 7 to 9 and designated at 40with the inner and outer shells of the barrell Thebushing' lllisconventional in its construction except for the provision of a recess 41toreceive a flanged up portion 42 of the inner shell; Portion 42 iswelded as at 42 to the bushing 40. The bushing 40 also has its outerperiphery at its inner end welded to the inner shell as indicated at 43The outer end portion of the bushing is received'in an opening in theouter shell or jacket J, which opening is designated at 44 and indicatedin dotted'linesinFigure 9. The portion of the outer shell surroundingthe outer end of the bushing is displaced inwardly slightly and thenwelded to the'bushing as indicated at 45. After'the welds are formedthey are smoothed down in a suitableman'ner so as to leave a smoothflush surface.

WhileI have shown and described several constructions in which theinvention may be advantageously embodied, it is to be understood thatthese constructions have been selected merely for the purpose ofillustration or example, and that various changes in the size, shape andarrangement of the parts may be made without departing from the spiritof the invention or the scope of the subjoined claims.

The invention claimed is:

1. A container of the character described comprising inner and outershells, the inner and outer shells being made up of tub-like sectionswelded together in the assembly, a tap bushing welded to the upper endheads of the inner and outer shells, a hung bushing weldedto the bodyportions of the inner and router shells, a plate welded to the lower endhead of the inner shell in vertical alinement with the tap bushing, thelower end head of the outer shell having an opening underlying saidplate and a Weld between the margin of the opening and said plate.

2. A metal container of the character described comprising inner andouter shells, means for securing the shells in spaced relation and anauxiliary support and connection between the shells comprising a platewelded to the inner shell,

the outer shell having an opening overlying the 10 plate, and a weldbetween the margin of said opening and said plate.
